High Res & Accuracy, Compensated Pressure Sensor

Product Announcement from Honeywell Sensing and Internet of Things


Honeywell’s Miniature Board-Mount Pressure Sensor!

 

The RSC Series is a piezoresistive silicon pressure sensor offering a digital output for reading pressure over the specified full scale pressure span and temperature range. It is calibrated and temperature compensated for sensor offset, sensitivity, temperature effects, and non-linearity using a 24-bit analog-to-digital converter with integrated EEPROM. Pressure data may be acquired at rates between 20 and 2000 samples per second over an SPI interface. It is intended for use with non-corrosive, non-ionic gases, such as air and other dry gases, designed and manufactured according to ISO 9001 standards, and is REACH and RoHS compliant.

 

DIFFERENTIATION

  • Industry-leading long-term stability: Minimizes system calibration needs and significantly reduces downtime.

  • Industry-leading accuracy: Reduces software to correct system inaccuracies, which minimizes design time, helps improve efficiency, and often simplifies development.

  • Industry-leading flexibility: Modular design with many package styles and options simplify integration.

  • Total Error Band: Provides true performance over the compensated temperature range, which eliminates the need to test and calibrate every sensor, thereby reducing manufacturing cost. Improves system accuracy and offers ease of sensor interchangeability due to minimal part-to-part variation

 

FEATURES:  

  • Pressure range: ±1.6 mbar to ±10 bar | ±160 Pa to ±1 MPa | ±0.5 inH2O to ±150 psi; absolute range 1 bar to 8 bar | 15 psi to 150 psi

  • Pressure types: Absolute: internal vacuum reference and an output value proportional to absolute pressure; Gage: referenced to atmospheric pressure and provide an output proportional to pressure variations from atmosphere; Differential: allows measurement of pressure between the two pressure ports

  • Total Error Band: As low as ±0.25 %FSS depending on pressure range (after auto zero)

  • Accuracy: ±0.1 %FSS BFSL (Full Scale Span Best Fit Straight Line)

  • Compensated temperature range: -40 ºC to 85 ºC [-40 ºF to 185 ºF]

  • Power consumption: Less than 10 mW, typ.

  • Size: Miniature 10 mm x 12,5 mm [0.39 in x 0.49 in] package

  • Output: 24-bit digital SPI-compatible

  • Meets IPC/JEDEC J-STD-020D.1 Moisture Sensitivity Level 1 requirements
